Application iiled December 14, 1901. Serial No. 85,879. (No model.)
This invention relates to an im proved com-- bined filter and precipitatingy tank in which the precipitating-compartment is arranged above the filtering compartment; andthe object of the invention is to simplify and cheapen apparatuses of this character bycombining the precipitating and filtering devices in one and the same vessel or tank. The invention also relates to certain details ofk construction, all of which will be lfully and clearly hereinafter described and claimed, reference being had to the accompanying drawings, in which- A Figure 1 is a top plan view of a pair of the improved filters connected together by suitable piping. Fig. 2 is a side elevation of the same. Fig. 3 is a section on line a a, Fig. 1.
Fig. 4 is a detached bottom view lof the vertical connecting-tube. Fig. 5 is a detached Fig. 6 is a fragmentary section on lineb b, Fig. 3. Fig. 7 is a detached vertical section through a three-way valve. i v
In referring to the drawings in detail like characters designate like parts.
In the preferred` construction of the invention shown in thedrawings two upright and closed vessels or tanks are coupledtogether, and as these tanks are slightly different in construction onewill be designated by the letter A and the other` by the letter B.
The vessel or tank A is divided into two compartments 1 and 2 by a partition or diaphragm 3, which is concaved or dished, 4as shown in Fig. 3. The lower andlarger compartment 1 has a horizontal plate 4., arranged slightly above the bottom of the vessel ortank, which is provided with slots5', and a series of strainer-plates 6, provided with narrow slits 7, are secured to the plate 4 above the slots 5.
The'compartment 1 is filled or nearly lled with granular filtering material 8, which is supported upon the plate 4:. The upper compartment 2, which is the mixing and precipitating compartment, has a top opening 9, and
in the dished diaphragm.
The vessel A is4 connected to the vessel B by a tubular connection or pipe 13. The vessel or tank B is similar tol the vesselor tank A withthe exception that `the central tube 10 is dispensed with and in lieu thereof a plate 14:, of curved cross-section, is riveted to the inner surface of the vessel or tank to form a vertical water-conducting passage 15. This plate extends to the top of the tank or vessel, and .a horizontal detlecting-plate 16 is suspended beneath its lower extreme by vertical connections 17 and serves to deflect the water as it leaves the passage 15. tends into communication with the passage 15, so that the precipitating-compartment in tank B communicates directlywith the pre` cipitating-compartment in tank A. A pipe 18 for supplying the first precipitating chemical to the water connects with the Water-sup-` end to the upper extreme of a vertical pipe 23, and the lower ends of the vertical pipes?^`y are secured to three-way valve connections 24, formed substantially as shown in Fig. 7.
lAn intermediate horizontal pipe connects the two three-way valves 24, and horizontal pipes 26, extending from the filtering-compartments, are coupled to the lower connec- The pipe 13 ex-4 heavier particles of impurities which collect Y connected by ICO tions of the three-wayvalves.V The upper cation with the vessels or tanks A and B below the plate 4. A horizontal pipe 33 eX- tends from each of the horizontal pipes 32 and has a shut-oft' valve 34. Two of these pipes 33 are employed, and each is connected to the horizontal pipe 29 by vertical pipes 35. Each of the vertical pipes 35 has a shut-oft valve 36.
The vessels or tanks are provided with several test-tubes 37, 3S, and 39, which connect with the various points, and have faucets 40, 41, and 42, through which the water may be drawn at different stages in the precipitation purification to ascertain the quality of the work. The vessels or tanks can be provided with manholes and openings 43 at various points for convenient access to the interior for repair or replacement.
The operation is as follows: The Water passes into the precipitating-compartment in tank A through the tube 10, being supplied with precipitating chemicals before it enters the compartment by the pipe 18, as before described. From the precipitating-compartment in tank A it passes through the connecting-pipe 13 into the precipitating-compartment in tank B, being supplied with the second precipitating chemical as it passes through the pipe 13, as before described. From the precipitating-compartment in tank B it passes out through the pipe 27into and through the horizontal and vertical pipes 22 and 23 and into and through the horizontal pipes 26 into the two filtering-compartments, where it is filtered. The filtered water is drawn from the filtering compartments through the pipes 29, 31, and 32, and is conducted to the desired point by piping connected to the vertical pipe 30. In operating the filters the disks 44 of the three-way valves are closed against the seat 45 to permit the water to pass into the filtering-compartment and prevent the water iiowing into the waste. When it is desired to clean out one of the filtering-com partmen ts, the disk 44 of the threeway valve of that filtering-compartment is moved to bring it against the seat 46, or substantially in the position shown in Fig. 7, thereby shutting oft the passage of water from the precipitating-compartments into that filtering-compartment and opening a passage from the filter-top into the waste-pipe. The heavier impurities collected in the dished diaphragm 3 are removed through the blow-out pipes 12 when the shut-off Valves 47 are opened.
The principal advantages -of this improvement arethat vby coupling two tanksf of this character together two precipitating-compartments and two filtering-compartments are obtained, and at the same time but two tanks or vessels are required, thereby greatly simplifying andcheapening the apparatus.
I claim as my invention` 1. A plurality of combined precipitating and filtering tanks coupled together and each divided into two compartments by a solid diaphragm, one of said compartments containing filtering material and the other constituting a precipitating-compartmeut, and means whereby the liquid to be purified passes through the precipitating-compartments of the tanks and then through the filtering-compartments, substantially as set forth.
2.

A combined precipitating and filtering tank having a top opening, a solid imperferate dished diaphragm dividing said tank into upper and` lower compartments, one of said compartments containing ltering material and the other constituting a precipitatingcompartment, a tube extending from the top opening into the precipitating-compartment and a defiecting-plate suspended from said tube.
4. A pair of filters coupled together and each divided into lower filtering-compartments and upper precipitating-compartments ICO and piping connecting one of said precipitating-compartments with the filtering-compartments.
